SEO is not ( just ) dead but already buried

All I see here is the real death ( and burial ) of organic search results in the visible part of the first page of Google SERP

Like this ↓ is not enough

but imagine one ( or all 3 ) top advertisers adding few sitelinks to that enhanced campaigns and that's it folks - no more organic results.

Of course all this Google moves to take for itself as much as possible from the SERP's real estate could've been easily predicted if one remembers the so called golden triangle first researched by Google back in 2009 ↓

or, in their own words :

This pattern suggests that the order in which Google returned the results was successful; most users found what they were looking for among the first two results and they never needed to go further down the page.
